Description

The specimen is from a small recent discovery. It is developed as floater. The feldspat is sharp terminated and snowy white. The fluorite is of high translucency and shows a neon sea-green colored stepped crystal. Further you can see some red-brown discs of siderite and thin tiny needles of schorl are intergrown inside the fluorite. A really fantastic thumbnail, highly aesthetic and great in each position.
